INERTIAL MEASUREMENT UNIT DERIVED INVERSE KINEMATICS DETECT AGE- AND KNEE OA-RELATED DIFFERENCES IN GAIT

Abstract

Purpose: Knee osteoarthritis (OA) structural and symptomatic severities are associated with and affected by gait mechanics. Studies of gait mechanics are typically performed in laboratories using marker-based motion capture, where participants walk at controlled speeds in a standard setting. While controlled procedures and settings allow precise quantification, in-lab gait may not represent daily, real-world gait. Quantifying the gait mechanics that individuals use to navigate daily life ostensibly would provide a more complete picture of the role of gait mechanics in the progression of knee OA.
